Revelations that a Doctor Who movie is in the pipeline may be premature. And if it does happen, don't expect a Hollywood A-lister to be shoehorned into the role, says showrunner Steven Moffat. "It's an incredibly exciting idea ... but if and when the movie happens it will need to star television's Doctor Who – and there's only ever one of those at a time," says Moffat in the Sun. Moffat said Harry Potter director David Yates – who revealed plans for the big-screen Who – was "talking off the cuff and a little prematurely". Clearly got the present mixed up with the future. Easily done.
